Light signals are transmitted through optical fibers using a process called optical communication, which involves sending light pulses through thin strands of glass or plastic fibers. Here’s how the process works:
The origin point generating intense light pulses for transmission.
The process of modulating light pulses to encode information.
Introduction of modulated light pulses into the core of an optical fiber.
Phenomenon where light repeatedly bounces within the core of the optical fiber due to refractive index differences.
Travel of light pulses through the fiber via total internal reflection.
Loss of signal strength and slight separation of different wavelengths due to scattering and other factors.
Detection of light pulses at the receiving end and extraction of original information through demodulation.
Strengthening of received signal and reduction of noise or distortions through processing.
Utilization of the processed signal for various applications such as sound reproduction or data display.
